Hi,
It seems bullet, when building on amd64 architecture, is not built with -fPIC...
Which leads to :
/usr/bin/ld: /usr/local/lib/libBulletDynamics.a(btTypedConstraint.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libBulletDynamics.a: could not read symbols: Bad value
when building shared libraries with Bullet on amd64.
It s explained nicely there (3.g) : http://www.gentoo.org/proj/en/base/amd6 ... t=1&chap=3
